Craftsman 319190630 bench grinder Parts

A Craftsman bench grinder is a stationary power tool (like the Craftsman model 319190630) that spins abrasive wheels to sharpen tools, shape metal, remove rust, and smooth rough edges. It is designed to mount to a workbench for stable, controlled grinding.

What you typically use it for

• Sharpening blades and cutting tools (chisels, mower blades, axes)
• Deburring metal after cutting or drilling
• Cleaning up welds and smoothing rough edges
• Removing light rust or paint (with the correct wheel or accessory)
• Shaping small metal parts for fit and finish

Key parts and features you will see on most bench grinders

Even without model-specific documentation for 319190630, most Craftsman bench grinders share these common components:

Feature	What it does	Why it helps
Grinding wheels	Abrade metal to sharpen or shape	Controls how fast and how smooth material is removed
Wheel guards	Cover the wheel sides and contain debris	Improves safety and keeps sparks directed
Tool rests	Support the workpiece near the wheel	Helps keep angles consistent while sharpening
Eye shields/spark deflectors	Block debris and redirect sparks	Protects your face and improves visibility
On/off switch and power cord	Controls power to the motor	Enables quick shutoff when needed

Safe, effective basics (what we recommend)

• Mount the grinder securely to a solid bench before use.
• Use the correct wheel type and grit for the material and task.
• Keep the tool rest close to the wheel (a small gap) so workpieces cannot wedge.
• Let the wheel do the work; avoid forcing the metal into the wheel.
• Inspect wheels for cracks and damage before grinding.

Why it matters

A bench grinder is one of the most useful shop tools because it restores sharp edges and cleans up metal quickly. Using the right setup and technique improves results and reduces the chance of wheel damage or kickback.

Yes, you can run the Craftsman 319190630 bench grinder with only one wheel installed, as long as the remaining wheel is mounted correctly and the guards and tool rests are secure. Expect faster spin-up and less flywheel effect, so the grinder can bog down sooner under heavy pressure.

What changes when you remove one wheel

Running with one wheel mainly changes how the grinder behaves, not whether it will run.

• Less rotating mass (inertia): it reaches full speed faster.
• Less momentum under load: it slows down faster if you push hard.
• Different feel at startup and shutdown: coasts for a shorter time.
• More temptation to overuse one side: the remaining wheel can wear faster.
• Higher importance of correct mounting: a poorly seated wheel can vibrate and crack.

Safety checks before you power it on

A bench grinder wheel can fail violently, so setup matters more than “can it run.”

• Unplug the grinder before changing wheels.
• Confirm the wheel is the correct diameter, thickness, and arbor size for the grinder.
• Make sure flanges/washers are installed in the correct order and fully seated.
• Set the tool rest gap close (typically about 1/8 inch) so workpieces cannot wedge.
• Set the spark guard/tongue guard close (typically about 1/4 inch) to limit kickback.
• Stand to one side at startup and let it run about a minute before grinding.

Quick comparison: one wheel vs. two wheels

Setup	Best for	Tradeoff
One wheel installed	Temporary use while replacing a damaged wheel	Less momentum; easier to stall under pressure
Two wheels installed	Normal grinding and balancing left/right tasks	Slower spin-up; more stored energy

Why it matters

If one wheel is damaged, removing it is safer than running it “just to finish a job.” A cracked or out-of-round wheel can cause severe vibration, poor grinding results, and wheel failure.

For the Craftsman 319190630 bench grinder, the 4 most important rules are: wear proper eye and face protection, keep guards and tool rests correctly adjusted, use the correct grinding wheel and speed rating, and keep hands, clothing, and hair safely away from the wheel at all times.

The 4 rules (with the key details that make them work)

• Protect your eyes and face every time: wear safety glasses plus a face shield; grinding wheels can throw sparks, grit, and fragments.
• Set the guards and tool rest before you start: keep the work rest close to the wheel (commonly about 1/8 inch) and keep the spark guard close as well so the work cannot get pulled into a gap.
• Match the wheel to the grinder: only use a wheel that is rated at or above the grinder’s RPM, and use the correct wheel type for the material (typical choices are aluminum oxide for steel and silicon carbide for masonry).
• Control entanglement and hand safety: no loose sleeves, gloves, jewelry, or dangling cords near the wheel; tie back long hair and keep a stable stance with both hands controlling the workpiece.

Quick pre-start checklist (bench grinder safety)

• Unplug the grinder before adjusting guards, tool rests, or wheels.
• Inspect the wheel for chips or cracks; replace damaged wheels immediately.
• Confirm the wheel is tight and runs true; start the grinder and let it reach full speed.
• Stand slightly to one side at startup (not directly in front of the wheel).
• Grind on the face of the wheel (not the side) unless the wheel is specifically designed for side grinding.

Common settings and limits (typical guidance)

Item	Typical safe target	Why it matters
Tool rest gap	~1/8 in.	Reduces the chance the workpiece wedges and kicks back
Wheel RPM rating	Grinder RPM or higher	Prevents wheel overspeed failure
Startup position	Off to the side	Lowers risk if a wheel fails at startup

Why it matters

A bench grinder spins an abrasive wheel at high speed; small setup errors (a wide tool-rest gap, wrong wheel rating, or loose clothing) can turn a routine sharpening job into a sudden kickback or wheel failure.

Most bench grinders run in the 1/3 HP to 1 HP range. For the Craftsman 319190630 bench grinder, use the motor nameplate (amps, volts, RPM) to determine the exact horsepower; many 6-inch Craftsman grinders are in the light-duty 1/3 HP class.

Typical HP ranges (what to expect)

• 1/3 HP: sharpening, deburring, light grinding with short passes
• 1/2 HP: general-purpose grinding with moderate pressure
• 3/4 HP to 1 HP: frequent grinding, heavier stock removal, less bogging
• Over 1 HP: specialty or industrial use (larger wheels, long duty cycles)

How to confirm HP on model 319190630

The most accurate way is to read the motor plate and convert from electrical ratings.

• Look for amps (A) and volts (V) on the motor label
• Note whether it is 120V or 240V
• Record RPM (helps confirm you are reading the correct label)
• Use the grinder as intended; higher pressure does not equal faster grinding

What you have	What it tells you	What to do next
HP listed on label	Exact horsepower	Use that value for comparisons
Only amps and volts listed	Lets you estimate motor size	Compare to typical 1/3 HP to 1 HP ranges
Grinder bogs down easily	Load exceeds motor capability	Use lighter passes, dress wheel, consider higher-HP grinder for heavy work

Why it matters

Horsepower is what keeps wheel speed from dropping under load. Matching HP to your grinding style reduces stalling, overheating, and excessive wheel glazing.
